Effect Of Paternity Test Results:

1. Effect of results. The results of the tests required pursuant to section 1558 are evidence to be used in determining paternity as follows.
A. If the court finds that the conclusion of all the experts, as disclosed by the evidence based upon the tests, is that
the alleged father is not the parent of the child, the question of paternity must be resolved accordingly.
B. If the experts disagree in their findings or conclusions, the question must be submitted upon all the evidence.
C. If the experts conclude that the blood or tissue tests show that the alleged father is not excluded and that the probability of the alleged father’s paternity is less than 97%, this evidence must be admitted by the court and weighed with other competent evidence of paternity.
D. If the experts conclude that the blood or tissue tests show that the alleged father is not excluded and that the probability of the alleged father’s paternity is 97% or higher, the alleged father is presumed to be the father, and this evidence must be admitted.

The court shall admit as evidence the results of any genetic test that is of a type generally acknowledged as reliable by accreditation bodies designated by the federal Secretary of the Department of Health and Human Services and performed by a laboratory approved by such an accredited body.

2. Chain of custody; evidence. Notarized documentation of the chain of custody of the blood and tissue samples is competent evidence to establish the chain of custody.

3. Notarized reports; challenges. A notarized report of the blood and tissue tests, prepared by the appointed experts, must be admitted at trial, unless a written challenge to the testing procedure or the results of the blood and tissue tests has been filed with the court and delivered to opposing counsel at least 30 days before a hearing set to determine the issue of paternity. Failure to make that timely challenge constitutes a waiver of the right to have the experts appear in person and is not grounds for a continuance of the hearing to determine paternity. [More]
